Read all instructions before using this product! 1. Keep work area clean. Cluttered areas invite injuries. 2. Observe work area conditions. Do not use machines or power tools in damp or wet locations. Don’t expose to rain. Keep work area well lighted. Do not use electrically powered compressors in the presence of flammable gases or liquids. 3. Keep children away. Children must never be allowed in the work area. Do not let them handle machines, tools, extension cords, or air hoses. 4. Store idle equipment. When not in use, tools must be stored in a dry location to inhibit rust. Always lock up tools and keep out of reach of children. 5. Use the right tool for the job. Do not attempt to force a small tool or attachment to do the work of a larger industrial tool. There are certain applications for which this tool was designed. It will do the job better and more safely at the rate for which it was intended. Do not modify this tool and do not use this tool for a purpose for which it was not intended. 6. Dress properly. Do not wear loose clothing or jewelry as they can be caught in moving parts. Protective, electrically nonconductive clothes and nonskid footwear are recommended when working. Wear restrictive hair covering to contain long hair. SKU 93566 For technical questions please call 1-800-444-3353. Page 2 Use eye and ear protection. Always wear ANSI approved impact safety goggles and hearing protection. Wear a full face shield if you are producing metal filings or wood chips. Wear an ANSI approved dust mask or respirator when working around metal, wood, and chemical dusts and mists. 7. 8. Do not overreach. Keep proper footing and balance at all times. Do not reach over or across running machines or air hoses. 9. Maintain tools with care. Keep tools clean for better and safer performance. Follow instructions for lubricating and changing accessories. Inspect tool cords and air hoses periodically and, if damaged, have them repaired by an authorized technician. The handles must be kept clean, dry, and free from oil and grease at all times. 10. Disconnect air supply. Disconnect air hose when not in use. 11. Remove adjusting keys and wrenches. Check that keys and adjusting wrenches are removed from the tool or machine work surface before plugging it in. 12. Avoid unintentional starting. Be sure the trigger is released when not in use and before plugging in. Do not carry any tool with your finger on the trigger, whether it is plugged in or not. 13. Stay alert. Watch what you are doing, use common sense. Do not operate any tool when you are tired. 14. Check for damaged parts. Before using any tool, any part that appears damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment and binding of moving parts; any broken parts or mounting fixtures; and any other condition that may affect proper operation. Any part that is damaged should be properly repaired or replaced by a qualified technician. Do not use the tool if any switch does not turn On and Off properly. 15. Guard against electric shock. Prevent body contact with grounded surfaces such as pipes, radiators, ranges, and refrigerator enclosures. 16. Replacement parts and accessories. When servicing, use only identical replacement parts. Use of any other parts will void the warranty. Only use accessories intended for use with this tool. Approved accessories are available from Harbor Freight Tools. 17. Do not operate tool if under the influence of alcohol or drugs. Read warning labels if taking prescription medicine to determine if your judgement or reflexes are impaired while taking drugs. If there is any doubt, do not operate the Wrench. 18. Use proper size and type extension cord. If an extension cord is required, it must be of the proper size and type to supply the correct current to the compressor without heating up. Otherwise, the extension cord could melt and catch fire, or cause electrical damage to the compressor. Check your air compressor’s manual for the appropriate size cord. 19. Maintenance. For your safety, maintenance should be performed regularly by a qualified technician. 20. Compressed air only. Never use combustible gas as a power source. 21. This Impact Wrench should only be used with impact sockets and extensions. Using any other accessories can cause the accessories to break, causing permanent damage to the unit and severe injury to the operator, property or bystanders.

Extension cord usage may also affect tool performance. WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities, contain chemicals known [to the State of California] to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are: • Lead from lead-based paints • Crystalline silica from bricks and cement or other masonry products • Arsenic and chromium from chemically treated lumber Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles. (California Health & Safety Code 25249.5, et seq. ) Warning: The warnings, cautions, and instructions discussed in this instruction manual cannot cover all possible conditions and situations that may occur. It must be understood by the operator that common sense and caution are factors which cannot be built into this product, but must be supplied by the operator. Unpacking When unpacking, check to make sure the parts listed on page 7 are included. If any parts are missing or broken, please call HARBOR FREIGHT TOOLS at 1-800-444-3353. Operation Impact Wrench with Extended Anvil For best service you should incorporate an oiler, regulator, and inline filter, as shown in the diagram above. Hoses, couplers, oilers, regulators, and filters are all available at Harbor Freight Tools. 1. You will need to prepare a 1/4” air connector (not included) to connect to the Air Inlet (10) on the Impact Wrench. First, wrap the 1/4” air connector with pipe thread seal tape before threading it into the Air Inlet (10). Connect the 1/2” ID Air Source Hose to a quick connect coupler (not included), and then to the Impact Wrench. Note: If you are not using an automatic oiler system, before operation, add a few drops of Pneumatic Tool Oil to the airline connection. Add a few drops more after each hour of continual use. 2. Set the air pressure on the regulator to 90 PSI. Do not exceed the recommended air pressure of 90 PSI. 3. Check the air connection for leaks. Disconnect from the air source. SKU 93566 For technical questions please call 1-800-444-3353. Page 4 Operation (continued) Warning!! This Impact Wrench supplies powerful torque and is designed to be operated with two hands. Failure to operate the Impact Wrench with two hands may result in serious injury. Refer to FIGURES 1 through 3 on page 6, and the Assembly Drawing on page 8. Note: Turn off your air compressor and disconnect the air hose when you are changing sockets. After you attach the socket, attach the air hose and turn the air compressor on. 4. Select the appropriate size 1/2” drive socket (not included) for your needs. 5. Push and snap the socket onto the Anvil (18). 6. To operate the Air Regulator (12), follow the directions in FIGURE 2 on page 6. Note: Set the Forward/Reverse Valve (3) so that the Anvil (18) turns clockwise (forward) - see FIGURE 3 on page 6. 7. Tighten the nut as tight as you can by hand. 8. Place the socket over the nut you wish to tighten. 9. Grip the Impact Wrench firmly with two hands and gently squeeze the Trigger (4). Note: If the Impact Wrench cannot tighten the nut to your satisfaction, do not raise the air pressure on the compressor over 90 PSI. Pressures above 90 PSI will strip the workpiece and damage the tool, potentially causing the tool to fail, causing serious injury. Use other appropriate methods and tools to tighten the nut. 10. When the nut is tightened, release the Trigger (4). Turn off the air compressor and disconnect the hose. 11. If available, check the recommended torque specification for the nut. Use a torque wrench to tighten the nut to the proper setting after using the Impact Wrench. Loosening Note: Set the Forward/ Reverse Valve (3) so that the anvil turns counterclockwise (reverse)- see Figure 3. 12. Place the socket (not included) over the nut you wish to loosen. 13. Grip the Impact Wrench firmly with two hands and gently squeeze the Trigger (4). Note: If the Impact Wrench cannot loosen the nut, do not raise the air pressure on the compressor over 90 PSI. Do not attempt to loosen the nut with the Impact Wrench. Use other appropriate methods and tools to loosen the nut. 14. When the nut is loosened, release the Trigger (4). Turn off the air compressor and disconnect the hose. 15. If needed, remove the nut from the socket. Maintenance 1. Make sure your Impact Wrench is disconnected from the air hose before attempting any maintenance. 2. Wipe the Impact Wrench down with a lint free cloth after each use. 3. Make sure the Anvil (18) is clear of dirt or debris. If possible, spray it with compressed air before each use. SKU 93566 For technical questions please call 1-800-444-3353. Page 5 Maintenance (Cont’d) 4. Weekly, or more often if used on a daily basis, use a grease gun (not included), to inject grease into the Grease Fitting. Put in only a drop or two. See FIGURE 3. 5. If you do not use an inline oiler/filter system, lubricate the tool daily by holding it so that the Air Inlet (10) is facing up. Squeeze the Trigger (4), and place one or two drops of oil into the Air Inlet (10). Squeezing the Trigger (4) allows the oil to circulate in the motor.
